A method for dyeing keratinous material, in particular human hair, may include applying a first agent to the keratinous material. The first agent may include hydrogen peroxide. The method may further include applying a second agent to the keratinous material. The second agent may include at least one organosilicon compound from the group of silanes having one, two, or three silicon atoms. The method may further include applying a third agent to the keratinous material where the third agent includes at least one sealing reagent. At least one of the second or third agents may further include at least one dyeing compound from the group consisting of pigments and/or direct dyes.

Method for dyeing keratinous material, comprising the use of an organosilicon compound, a dyeing compound, a sealing reagent, and a pre-treatment agent

A method for dyeing keratinous material, such as human hair, may include applying a first agent to the keratinous material. The first agent may include at least one organosilicon compound from the group of silanes having one, two, or three silicon atoms, and at least one dyeing compound from the group of pigments and/or direct dyes. The method may further include applying a second agent to the keratinous material. The second agent may include at least one film-forming polymer. The method may also include applying a third agent to the keratinous material where the third agent may include a hydroxyamine-functionalized silicone polymer having the INCI name 'Bis-Diisopropanolamino-PG-Propyl Disiloxane/Bis-Vinyl Dimethicone Copolymer'. At least one of the first and/or the second agents may include at least one dyeing compound from the group consisting of pigments and/or direct dyes.

Method for dyeing keratinous material, comprising the use of an organosilicon compound, a dyeing compound, a sealing reagent, and a polymer-containing post-treatment agent

A pigment suspension, a cometic agent obtainable from a pigment suspension, and a kit-of-parts containing a pigment suspension are provided.
